* there is no library function called sched_prio(), so this manual pagederaadt2010-11-072-6/+5

* Change basep parameter of getdirentries() to be off_t *, not long *millert2010-10-283-6/+6
| | | | | | | | so it works correctly with large offsets (and matches other systems). This requires adding a new getdirentries syscall, with the old one renamed to ogetdirentries. All in-tree consumers of getdirentries() have been updated. Bump libc and libpthread major numbers. OK and with deraadt@
* Fix PR 6417: if we're starting a thread and there's no other threadsguenther2010-07-131-2/+3
| | | | | | | running, then we need to start a gc thread...except when this is the very call to start a gc thread! "This works for me" marc@
* Fix PR 6376: restore more thread library state if execve fails,guenther2010-07-133-46/+55
| | | | | | | including the scheduling timer, sigmask, fd nonblocking status, and handling of the signals used by the thread library. ok marc@, additional testing by ajacoutot@
* After forking, clear the 'thread joining this one' pointer in the child,guenther2010-07-121-1/+4
| | | | | | as the child only has the one thread remaining. ok marc@
* Use __attribute__ ((aligned (16)), to make sure the FPU state is alignedkettenis2010-06-301-3/+3
| | | | | | | | | on a 128-bit boundary like we do on amd64. The padding within the struct made sure the state was properly aligned *within* the struct, but since the alignment restriction on the struct itself was only 64-bit, the required alignment was not guaranteed. We just got lucky. ok oga@, guenther@
* Instead of (manually) closing the _thread_kern_pipe before callingguenther2010-06-272-6/+20

* Make internal file descriptor handling async-signal safe by eliminatingkurt2009-12-0611-83/+124
| | | | | | the use of spinlocks and malloc. All needed memory is allocated upfront and _thread_kern_sig_defer/undefer() is now used to protect critical sections. okay guenther@
* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-131/+122
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.

* Change libpthread's f*lockfile() routines to stop acting as no-opsguenther2009-10-211-131/+122
| | | | | | | | | for FILEs that don't have real file-descriptors: the fake FILEs used internally by snprintf/asprintf/vfprintf and friends now avoid unnecessary locking by calling the internal __vfprintf() routine directly and we do want to do locking on FILEs created with funopen(). ok kurt@
